Make sure sound's actually enabled under Game Settings -> Audio, then if that doesn't work, make sure the SFX and BGM volumes are set to 8. Failing that, double check to make sure sound is working on your device in general (yes, I'm serious), and if applicable, that the in-game sound levels are on and turned up. If after that, it still doesn't work, then I would guess your ISO is bad, or we have some sort of Android bug with audio. Is sound working in other games in PPSSPP for you?

Is anyone else not able to see the prologue after you start a new game? It doesn't start up and stays a black screen, but it can still be skipped. Then gameplay starts but its play at about 19 fps. I'm using v.0.9.5-706 with default settings and a merged iso.

Anybody else encountered artifacts on any character after their death ? It's really annoying when your main hero is invisible, any fixes to that ? Using 0.9.6 on my PC - game runs good except for that weird graphical glitch.

As for low performance, enable Hardware Transform and Vertex Chace, should run solid 30.

Can anyone help me? On 0.8.1 i get past the loading screen to a blank screen. I can tell its not frozen because if i press "O" it tells me there is no saved data. On 0.9.6, past the loading screen I just get ppsspp not responding before it crashes. I only have this problem with disc 1, disc 2 has video and audio and all but of course I can't play because i have to start a new game on disc 1 first.
